Wow! Had to replace a hard drive in Chrissy's apple notebook tonight. Went pretty well. The Apple store wanted $300+ for the same size drive in the powerbook (37g), but I asked the 'genius' if I could install a drive myself if I wanted to, and he said yeah sure. So we got a Toshiba 60g drive for just under $100, and just followed the directions (found by a search of Apple's site) and we''re golden now. Reinstalling the OS (10.2) now and all will be right with the world.
